[Email protected] ~]# oracleasm scandisks
Reloading Disk Partitions:done
Cleaning any stale ASM disks ...
Scanning system for ASM disks ...
[Email protected] ~]#

Workaround:

The partition does not take effect because the RAC1 node format disk is not using the Partprobe command

In Rac1 execution:

[Email protected] ~]# Partprobe

In Rac2 execution:

[Email protected] ~]#/usr/sbin/oracleasm scandisks
Reloading Disk Partitions:done

2. Oracle_home and Oracle_base directories do not appear when installing the grid cluster software

Error message:

Ins-32026]the software location specified should not being under Oracle base location.
Cause:grid Infrastructure for a Cluster installation would assign root ownership to all parent directories of Clusterware Software location. As a result, all named directories in the software location path would acquire root ownership. This could create problems for subsequent installations into the same Oracle base.
Action:specify software location outside of Oracle base

Workaround:

My current directory is: Oracle_base=/home/grid

Oracle_home=/home/grid/11.2.0/grid

This directory is not correct, because the Oracle_base and Oracle_home directories to separate, Oracle_base installed after the root authority, and Oracle_home did not.

That's right: Oracle_base=/home/grid/app

Oracle_home=/home/grid/11.2.0/grid
